Signal device

SIGNAL DEVICE Application led August 19, 1927.y Serial No. 213,990.

This invention relates to signal devices and more particularly such asare used on motor be attached to existing motor vehicles with-V outdisturbing any of the conventional construction and capable ofselectively indicating the intention of the driver of the vehicle ..15equipped therewith. v

A further aim is in the provision of a novel means for illuminating` theindicating device to show a retarding of speed, a stop, a right turn, ora left turn.

which will become apparent as the description progresses, are attainedby the unique construction, combination and arrangement of parts,hereinafter described and illustrated in the associated drawing,constituting an important component of this disclosure, and in whichFigure 1 is a fragmentary,'perspective view of a conventional motorvehicle equipped so with an embodiment of this invention.

Figure 2 is a front elevational view of a signal device made inaccordance with this invention.

Figure 3 is a similar view of the same having the front plate removed toshow the wiring diagram.

Figure 4 is a transverse sectional view taken on line 4-4 of Figure 3.

Figure 5 is a similar view taken on line 5 5 of Figure 3.

In the drawing, the numeral 10 generally designates a conventional motorvehicle on the side of which, adjacent the drivers seat, is fixed abracket 11 carrying a casing 12.

The casing consists of a pair of transparent circular plates 13 on whichare marked by any preferred method, a double pointed arrow 14 and theword Stop 15.

The plates are held together by a pair of These several ob] ects,together with others,`

bands 16 around the rims thereof and are spaced by an annular band 17.

Formed in the casing are a plurality of compartments 16, 18, 19, 20, 21,22, 23, and 24, in which are respectively mounted bulbs 25, ,55 2e, 27,2s, 29, so and e1.

The vbulbs 25, 27, 28' and 30' eachhave one pole 32 thereof mounted inan insulating block 33 fixed to the inner wall of the respectivecompartments by a screw 34, the opposite pole 35 engaging a spring 36mounted in a socket 37 secured to the band 17, the latter forming aground.

The inner poles of the bulb 25 and 27 areconnected by an electricconductor 38, which in turn is connected by a wire 39 to a switch arm 40-engageable with a contact 41 connect-ed to one end of an electricbattery 42, the opposite end of which is grounded.

The innerpoles of the bulbs 28 and 30 are '70 connected by a conductor43 which in turn is connected to a wire 44 leading to a switch arm 45engageabl'e with the contact 46, also Aconnected to a source of current42.

Fixed to the band 17 in the compartments 275 19, 22 and 24 are brackets47 carrying the bulbs 26, 29 and 31, one pole of each bulb beingconnected through the bracket to the ground band 17. y

The lower poles of the bulb 26"and 29 arefgg connected by a conductor 48in contact-with a wire 49 attached to a switch arm 50 engageable withcontact 51 leading to the source of current 42 and the lower pole of thebulb 31 is connected by a wire 52 to a"g5 switch arm 53 engageable witha contact 54,

' also leading to the source ofl current supply 42.

The leads 39, 44 and 52 all pass downward through a tube 55 at thelowermost ypoint of'eo the casing 12.

Thus, if it is desired to indicate the intention of a retarding of thespeed of the vehicle, the driver engages the switch arm 50l with thecontact 51, completing the circuitb to illuminate the bulbs 26 and 29,which will show through the plates A13 to make the central portion ofthe double pointed arrow 14 appear lit, indicatingdrivers intention tothose in front or in the rearl olf the vehicle. 55100 By tracing thediagram shown in Figure 3, it will be also seen that by respectivelyclosing the switches 40-41, Ll-l and 53-54, the lights 25-27, 28-3() or31 will be illuminated to indicate a left or right turn or a stop, thesaine being shown on the plate 13 by the illumination of either end ofthe doublepointed arrowvll or the Word Stop.

From the foregoing, it is obvious that many accidents may be avoidedsince it will be possible for a drivel' to know just what the nextmovement of the vehicle in front of him will be'.

While the foregoing is descriptive of the preferred embodiment of myinvention in detail, it is not intended that the same be interpreted ina limiting sense, as changes in size, proportion, etc., may be madewithout departing from the spirit and scope of the appended spaced, agrounded band and sets of bulbs within said casing, insulated blockshaving one pole of the bulbs of two sets (25, 27, and 28, 30) `mountedtherein, grounded springs engaged by the other poles of said bulb sets,an

electric conductor connecting the inner polesv of the bulbs of one set(25, 27), a switch arm (40) connected to said conductor engageable witha contact connected with one pole of a source of electricity, having`its other pole grounded, a conductor connecting the inner poles of theother set of bulbs (28, 30), a second switch arm (45) connected to saidconductor and engageable with a contact connected with a source ofelectricity, a third set of bulbs (26, 29,) having one pole thereofconnected to said grounded band, a switch arm (50) to which the otherpoles of said set of bulbs are connected, said switch arm engageablewith a contact connected to a source of electricity, and a single bulb(81) also connected at one pole to said grounded ring, partitions insaid casing separating the same into a plurality of chambers, eachcontaining one bulb of said sets of bulbs and one of said chamber thelast named bulb to illuminate the word Stop, a switch arm (53) connectedto the other pole of said single bulb, said switch arm connected to acontact in connection with a source of electricity, said switch armsadapted to close the circuits in which said set of bulbs and the singlebulb is located to illuminate the word Stop and the double pointed arrowto indicate an intended stop, turns, and direction thereof and nature.
